Morris County emergency officials are warning there could be severe flooding and winds in the county Wednesday night, as the region gets hit by a powerful and complex storm.

The storm will approach over the next 12 to 18 hours, the Morris County Office of Emergency Management said around 4 p.m. Wednesday, and the main threat for flooding and winds is Wednesday night.

The storm may weaken before it hits the Morris County area, but could still produce rain showers toward sunset, and gusty winds, county OEM said.

Meteorologists are also ancitivpating a cold front will move through the area around midnight, and a widespread area of heavy rain will likely accompany it. That could be accompanied by winds in excess of 50 mph.

"The area of time that we are mostly concerned with based on data we have reviewed is between 10p and 5a. It is anticipated that the increased winds will follow into tomorrow," county OEM said in a news release. "We encourage you to be proactive and notify your residents to secure light-weight outdoor objects such as patio furniture, garbage cans and other items which may be vulnerable to increased winds."

Residents who experience any problems should contact their local police
